Jennifer Lopez explained, “I honestly feel like the time has come, that I have to get back to doing the other things that I do that I’ve put kind of on hold because I love ‘Idol.’ I could just keep doing ‘Idol’ for the rest of my life, but that would be giving up a bunch of other things. I feel like we had an amazing run.”

“I have my movies and music and my this and that … and it just gets more complicated, as the kids get a little bigger. It started feeling like it was a lot, and something had to give. And that’s, I think, where I am right now, she continued.

Randy Jackson is the only judge standing , with Steven Tyler and Jennifer Lopez not returning to “American Idol” next season.
